WebApr 11, 2024 · Intuitively, Fisher’s information gives us an estimate of how certain we are about the estimate of the parameter $\theta$. This can be seen by recognizing the apparent similarity between the definition of the covariance matrix we have defined above and the definition of Fisher’s information.

Fisher information can be used as an alternative to the Hessian of the loss function in second-order gradient descent network … See more In mathematical statistics, the Fisher information (sometimes simply called information ) is a way of measuring the amount of information that an observable random variable X carries about an unknown … See more When there are N parameters, so that θ is an N × 1 vector The FIM is a N × N See more Optimal design of experiments Fisher information is widely used in optimal experimental design. Because of the reciprocity of … See more The Fisher information was discussed by several early statisticians, notably F. Y. Edgeworth. For example, Savage says: "In it [Fisher information], he [Fisher] was to some extent anticipated (Edgeworth 1908–9 esp. 502, 507–8, 662, 677–8, 82–5 and … See more The Fisher information is a way of measuring the amount of information that an observable random variable $${\displaystyle X}$$ carries … See more Chain rule Similar to the entropy or mutual information, the Fisher information also possesses a chain rule decomposition. In particular, if X and Y are jointly … See more Fisher information is related to relative entropy. The relative entropy, or Kullback–Leibler divergence, between two distributions $${\displaystyle p}$$ and $${\displaystyle q}$$ can be written as $${\displaystyle KL(p:q)=\int p(x)\log {\frac {p(x)}{q(x)}}\,dx.}$$ See more Webcalculate the Fisher information in a sample of size n.
